摘要

对巴里坤湖ZK00A钻孔剖面用多种手段进行同步同周期的综合研究。古气候变化格局以各种不同时间尺度、不同程度的冷湿期和暖干期交替变化为特征。冷湿期与冰期、高湖面期对应;暖干期与间冰期、低湖面一致。整个剖面揭示出35000年来具有12个103年、3个104年、3个102年的气候旋回。其中12000年以来以暖干为主,12000年前以冷湿为主。存在着600、2225—2543、5933—8900、11600年的变化周期。对内陆干旱区,35000年以来的气候变化序列、格局和周期的研究,以大量气候标志、参数为依据,经计算机处理与成图,具有较高的可信性。

Abstract

Through a synthetical study on the profile of core ZKOOA in Balikun Lake with many kinds of means of synchronism, in this paper, we conclude the characteristic of climatic varia-tion pattern in arid area is that the cold-wet period alternated with the warm-dry period in different time scale to some degree, that cold-wet period corresponded respectively with the glacial age and high lake sureface, that warm-dry period with interglacial are and low lake surface The foundation and main reasons of the formation of this kind of climatic pattern are the distinctive inland arid environment situated in the middle latitude westerlies and ice melting water, So, this kind of climatic pattern has some universality in Xinjiang and arid area in the westerlies.
